BEA Ill-PLACING DI LVICE FOR USE IN BUILDING PNEUMATIC-TIRE SHOES.

Application filed June 2, 1916. Serial No. 101,287.

Y '1) //Z/ w/mm it may concern Be it known that I, MICHAEL PARIDON, acitizen of the United States, residing at Nortonavenue. Barberton, inthe county of Summit and State of Ohio, have invented new and usefulImprovements in -Bead-Placing Devices for Use in Building Pneumatic-TireShoes, of which the following is a specification.

This invention relates to devices for use in the building up of apneumatic-tire shoe and has a special relation o a device for securingthe accurate placement of the bead cores during the building operation.

The object of the invention is to provide a simple device by which thecores or reinforcing portions of the beads of pneumatic-tire-shoes maybe accurately and quickly positioned during the tire-shoe buildingoperation.

With the foregoing and other objects in view, the invention consists inthe novel construction, combination and arrangement of partsconstitutlng the invention to be hereinafter specifically described andillustrated in the accompanying drawings which form a part hereofwherein is shown the preferred embodimentof the inventidn, but it is tobe understood that changes, variations and modifications can be resortedto which come Within the scope of the matter hereinafter claimed.

In the drawings in which similar reference numerals indicate like partsin the dif-* ferent figures, Figure 1, is a vertical sectiontransversely of a core used for building pneumatic-tireshoes with aportion of a shoe thereon and also showing my device in operativerelation therewith, and Fig. 2, is a side elevation of a deviceembodying my invention.

The device which forms the subject mat},-

ter of this invention comprises a split ring .1 of partially resilientmaterial, provided with separated ends 2 having a normal ten dency toexpand outwardly or radially and furthermore, provided with an outerface of periphery 3 constituting a seat or gage positioning the beadcoresv The outer periphery 3 is furthermore provided with a rabbetcomprising a cylindrical face 4 and a radial face Adjacent to theseparated ends 2 the member is provided with operating handles 6.

.type provided with an inwardly-extending flange 11L Innsingthe devicethe outer face of thecore 10 is covered with one or more layers offabric or other strengthgiving material from which the tire-shoe is tobe constructed and while the core is suitably supported the handles 6and 7 are drawn toward each other to reduce the.

diameter of the cylindrical face 4 sufliciently to permit it to bepositioned within the inner face of thelflange 11 and when pressure isremoved from the handles of the member 1, it expands of its ownresilience causing the cylindrical face 4 to seat against the inner faceof the flange 11 and with the radial face 5 in lapping or contacting enagement with one of the side faces of the auge 11. By thus positioningthe member 1 the outer face 3 will provide a seat or gage extendingcircumferentially of the core-body and at a predetermined distance fromthe inner face of the flange 11 and constitutes an abutment and supportfor accurately positioning the beads 12 which are applied to the outerface of the strength-giving member 12 and are accurately located bymeans of the member 1. After positioning the beads 12 and causing themto adhere to the member 12 the member 1 is contracted in diameter andremoved from the core after which the balance of the tire-shoe is madeup in the usual manner.

It will be obvious, of course, that in building up a tire-shoe it willbe easier to simultaneously employ two similar members for positioningthe heads but it will be apparentthat a single member may be used byreversing its position and putting the bead cores on one at a time.
